Tunzes stopped pulsing!

[skriz]

Earlier today I notice that my tunzes weren't really pushing out much flow, I thought they may be dirty.

Just now, I noticed that the controller is not pulsing anymore. It shows the pumps to be at 30%. I can manually turn up the minimum dial and the pumps push and the scale goes up, but it won't pulse.

What should I try?

The usual culprit will be that the photocell fell in a dark area or the photocell socket got wet or shorted by salt creep, if it is a 7095 with a hardwired photocell it is also possible the photocell shorted from water entering the part itself.

looks like the photocell crept up and out of the light. thanks Roger, I was worried for a while!
